摘要: The invention relates to the field of natural gas hydrate exploitation, and discloses a method for exploiting hydrate. comprises steps that (1) first fluid is introduced into reservoir by at least one injection well obtain second dissolved with gas; (2) production leads ground or sea surfacefor gas-liquid separation (3) third led from replace residual and/or in reservoir, wherein contains oil 4-30 carbon atoms dynamic viscosity being 1-100 mPa.s mixture water. simple, convenient effective hydrate, meanwhile, does not disadvantageously cause geological disaster problems such as stratum collapse, ecological environment oceansand reservoirs are be damaged.
